As I could not find a better place for my suggestion although there is probably a better place I´ll post it here: I found out that ScreenshotCaptor remembers multiple hits of PrntScr. Like 10 times in a row within three seconds, which is a great feature anyway. The only drawback is that ScreenshotCaptor stops taking screenshots as soon as the screen didn´t change and displays an error message instead. Which happened only once, although I´m using ScreenshotCaptor a lot, maybe 1000 shots or more within four weeks.I´d prefer ScreenshotCaptor to continue taking screenshots. Maybe add an error message to the screenshots, but not stopping.

As far as I remember, it says that a screenshot is not sufficiently different from the preceding one. Maybe doesn´t differ in a single pixel. To the best of my memory. The message surprised me too much to record it.

SC doesn't care about differences in screenshots -- but SC will by default complain if you capture an entire image that is only one color.. This is a check to make sure something hasn't gone wrong. You can disable this option here in the "Miscellaneous Tweaks" tab:

@mouser: It took me quite a time to find out that I had to run the setup as admin. As my PC-dealer told me I´d have all possible rights on my private PC that didn´t occur to me. Anyway, there is no problem anymore. Whether to decide if this is a case of "problem solved" or "problem vanished" I don´t know. And the autostart-option takes some seconds before it is recognizable. That is i have to try some screenshots before I hear the meantime familiar click sound. @Kodezwerg: Dein Hinweis "Your Windows Admin Account may differ from Logon Account" war eigentlich goldrichtig. Ich habs nur nicht kapiert, weil mein Händler mir sagte, ich hätte alle Rechte. Ja, es gibt einen Unterschied zwischen Window Account und Logon Account. Bedauerlicherweise weisen weder Acronis noch Avast auf sowas hin.
